DS1 Tie Trunk Seizure Test (#136)
The DS1 Tie Trunk Seizure test is run to verify the trunk’s signaling capability. The test is
composed of two parts. The first part queries the circuit pack or media module for the following
errors: Loss of Signal, Red alarm, Blue alarm, Yellow alarm, and Hyperactivity alarm. The
second part of the test is performed by sending a seizure message to the DS1 Interface circuit
pack or media module and expecting an active reply by the DS1 Interface circuit pack or media
module. If maintenance software does not receive any reply and the timer expires, the test fails.
Once the active message is received, a dial pause message is sent to the DS1 Interface circuit
pack or media module. If the DS1 Interface circuit pack or media module replies with a dial
pulse tone message when the far end responds to the seizure, then the DS1 tie trunk Seizure
test passes. If the far end does not respond to the seizure and the timer expires, and the DS1
Interface circuit pack or media module sends a reorder message back to the maintenance
software, then the test fails.
This second part of this test cannot be run on a trunk if one of the following cases is true:
1. The trunk direction is administered as an incoming only trunk.
2. The trunk is the 24
th
port on a DS1 Interface circuit pack or media module which is
administered using 24
th
common-channel signaling.
3. The trunk has been seized by a normal trunk call.
4. The trunk is administered with maintenance test disabled.
5. The outgoing signal type of the trunk is either automatic or immediate-start.
This test always passes if the associated board is the TN802 IP trunk circuit pack.
